if some_fatal_condition:
log.error('Exiting due to fatal error foo:', dump)
kaa.main.quit()
elif type in (SystemExit, KeyboardInterrupt):
# User may choose not to quit mainloop on KeyboardInterrupt for
# some reason.
kaa.main.quit()
else:
# Unhandled exception but not a fatal condition, so we log it
# but don't quit the mainloop.
log.exception('Unhandled exception:', dump)
kaa.signals['exception'].connect(exception_handler)
kaa.main.run()
I also think that everywhere else in kaa that we're emitting on an
exception signal (for example Thread exception signal, InProgress
exception, etc), we should emit type, value, and traceback args for the
current exception. Like this:
try:
do_callback()
except Exception, exc:
self.signals['exception'].emit(exc.__class__, exc, sys.exc_traceback)
